 They're reasonably good sci-fi movies, but the character development is fantastic, and the friendship that she forges with this guy, Eric, is really touching. There's some really sweet moments here, and all three of these movies have done a terrific job with characterization. So, yeah, I mean, as these things go, if you're a fan of alien invasion movies, this is definitely on the better end of that spectrum. If you don't like lots of blood, probably take a pass on this one.
